Power Door Lock Switch: Description and Operation
CIRCUIT OPERATION
Left Door Switch Operation (Lock)
When the door lock switch is moved to the LOCK position, voltage is supplied on the P35 circuit to the bus bar located inside the right door
switch, lock side. Battery voltage is passed through the switch to the P33 circuit to the door motors. Grounding is provided through the P34 circuit
for all door motors back to the right door switch. The ground is passed through the bus bar internal to the switch, UNLOCK side, to the P36
circuit. The P36 circuit connects to the left front switch to a bus bar, internal to the switch, and then to the Z8 circuit. The Z8 circuit connects to its
grounding point.
Left Door Switch Operation (Unlock)
When the switch is moved to the UNLOCK position, voltage is supplied on the P36 circuit to the right door switch, unlock side. The battery
voltage is passed through the switch internal bus bar to the P34 circuit.
The P34 circuit then connects to the door motors on the unlock side. Grounding for the UNLOCK function is provided by the P33 circuit.
The P33 circuit connects back to the right door switch, LOCK side, and passes through the internal bus bar to the P35 circuit. The P35 circuit
connects back to the left door switch, and passes through the switch to the Z8 circuit. The Z8 circuit goes to it's grounding point.
Right Door Switch Operation (Lock)
When the switch is moved to the LOCK position, voltage is supplied to the P33 circuit, and then to the door lock motors. The ground path is
provided on the P34 circuit back to the right door switch. The ground is passed through the switch internal bus bar to the P36 circuit. The P36
circuit connects to the left door switch and through to the Z8 circuit.
The Z8 circuit then connects to the grounding point at the left center instrument panel support.
Right Door Switch Operation (Unlock)
When the switch is moved to the UNLOCK position voltage is supplied to the P34 circuit from the switch to the door UNLOCK side of the
motors. The grounding path is through the LOCK side of the motors, circuit P33, back to the switch. The ground continues through the internal
bus bar of the switch on circuit P35 to the left door switch. At the left door switch, the ground passes through that switches internal bus bar to the
Z8 grounding point.
